FEED-REGULATQR FOR GRlNDlNG-MILLS.

SPECIFICATION forming part of Letters Patent No. 396,058, dated January8, 1889.

Application filed April 23, 1887. $erial No. 235.849. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. VINCHELL, a citizen of the United States,residing at Sprin gfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Feed-Regulators forGrinding Mills, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in crushing and grinding mills,and is designed to reduce corn-cobs, (with and without the grain uponthem,) bark, bones, roots, and other substances first to a broken orcoarse state and then to such finer state as may be desired; and itconsists in combining an adjustable feedregulator with acrushing-chamber, whereby the rapidity of the passage of the materialfrom said chamber to the grinding mechanism proper may be controlled tosuit the different kinds of material and the different conditions whichmay arise from time to time in the practical use of the machine.

The mill generally is by preference of the general character shown anddescribed in Letters Patent granted to me May 18, 1886, and numbered$2,158, for crushing and grinding mills.

In the accompanying drawings, forming a part of this specification, and011 which like reference-letters indicate corresponding features, Figure1 represents a vertical sectional view of a mill of the character justalluded to, showing my improved feed-regulator in sections; Fig. 2, atransverse vertical sectional View through the hopper, thecrushing-chamber, and the crusher, showing the feed-regulator inelevation; Fig. 3, a plan view of a portion of the main casing, showingthe crushing-chamber and the feed-regulatortherein and its differentpositions; Fig. 4, an inverted plan View of that portion of the casingshown in Fig. 3, and also showing the means of adjusting thefeed-regulator.

The construction and arrangement of the frame, the casing, the mainshaft, and the grinding heads and plates, as also the adj ustingmechanism for the shaft, are the same in the present case as in myLetters Patent above alluded to. These features, however, may be variedat pleasure and some other form of frame and mechanism adopted.Therefore a minute description of the machine generally, exclusive ofthe feed-regulator and the crusher, is superfluous in this place.Furthermore, the machine generally is used interchangeably with thedevices peculiar to crushing comparatively large substances, the devicespeculiar to grinding cereals, and the devices peculiar to hulling seed.

Referring now to the peculiar features involved in the present case, theletter A designates the crushing-chamber, through which the materialpasses from the hopper on its way to the grinding mechanism proper, and

the letter B a series of bars, of which there are three in the presentinstance. These bars are fitted, as seen more clearly in Fig. 2, acrossthe bottom of the chamber A, the said bottom being flatter in this case,for the purpose of properly acting in conjunction with the bars, than inthe patent already alluded to. Formed in the bottom of the chamber are aseries of holes, and in each hole is fitted the shank or spindle O ofthe respective bars, the lower ends of which are preferably angular, asseen at D in Fig. 2, to receive an adj Listing-handle, E, and arms F,and are screw-threaded to receive nuts G. The arms F are connected withthe handle E by a pitman, H, through pivotal jointsv Secured to thecasing or forming a part of the general structure of the mill is anotched bar, I, with which the handle E is adapted to engage for thepurpose of locking the same in any set position. It will now be observedthat upon actuating the handle E more or less in one direction or theother the bars B will be adjusted at varying angles across thecrushing-chamber, and also that their general direction will be changed,as suggested by the full and the dotted lines in Fig. Now let itbesupposed that the crusher (to which reference will hereinafter be made)be revolved in the direction indicated by the arrow in Fig. 2, which isthe direction indicated by the arrow in Fig. 3, and the bars B areiaw eshown in the full lines in Fig. 3. will be very much less rapid in theposition shown in the dotted lines iii said .tigure. This is oneillustration of an eittreme dil'ferenee which. may be effected in thespeed of the feed of the mill. It will be understood, however, that avariation in the angle of the bars ll across the chamber, yet withoutehz'lngi ng their general direction, will also change the speed of thefeeifl. Thus my improved feed-regulat or will control the slow to feedfrom maximum. to minimum degree and the fast feed from maximum tominimum degree.

I have described what I consider to be the best means of carrying out myinvention; but

I wish to be distinctly understood as not in any sense eonlining myselfto this form of construction, since my invention is, broadly, that ofregulating the feed by a regulator located in the erushing-chamber andcapable 2o oi varying the speed of the feed.

The letter 1' refers to the crusher, the same being mounted on the mainshaft of the mill, and secured either in the manner set out in thepatent already alluded to or in any other way, and [)lUYltlttl withcrushing lugs or protuberances ii. These lugs I have shown with sidessubstantially parallel to the axis of the crusher, as being a formhighlyuseful in combination with my feed-regulator. The shape of theselugs, however, may be varied, and may be changed to the shape of thelugs shown in said patent. l have spoken of the crusher as a crusher,and of the chamber A as a erushing-ehaml)er, and. have used these termsfor the sake of harmony with the terms used in my said patent and othersre cited in it which have been granted to me; but it is not to beunderstood that if the crusher acted merely as a ti'onveyer and 40 thechamber as a eonveying-chamber a departure from my invention wouldtherebybe brought about. As a matter of fact, the organization hereshown and (hescribed accomplishes both the crushing and the conveying4.5 .Ifunetions, and. the bars 13 assist in the crushing operation while('zontrolling the speed of the feed operation. It will be furthernoticed that when the bars are in any given positimii they \irtuallybecome fixed, as distinguished from the adjustable, sothat ba rspermanently fixed to the chamberwould be but their equ i v alent withoutthe changes of adjustability. The plate 1h may or may not be used, andforms the same function as the plate K. in my Letters Patent alreadyreoitedto wit, that of lttllltjlllfl, the size of the clntmber, so as tocrush. eobs or substances much smaller than the average cob.

Having thus fully desm-ibed my invention, what I claim as new, anddesire to secure by Lott: rs Patent, is

1. In a mill, the combination, with a casing and a erushirig-chambercomposing a part of the frame thereof, a main. shaft rotatedlongitudinall y through the chamber and across the casing, and grindingmechanism in the casin near one end of the chamber, the rotatin partthereof being carried by said shaft, of a series of bars located acrossthe chamber, having shanks which extend through the wall of the chamber,a handle on one of them and arms on the others, a bar connecting thearms with the handle, and a locking device with which the handleengages, whereby the said bars may be adjusted and. held, and acylindrical body on the shaft having lugs or projections which eoactwith said. bars and crush the material and feed it to the grinding mechanism.

2. In a mill, the combination, with a casing and a crusiting-chambercomposing a part of the frame thereof, a main shaftrunninglongitudinally through the chamber and across the casing, and grindingmechanism in the cas ing near one end of the chamber, the rotating partthereof being Gitl'liOtl. by the said shaft, of a series of bars locatedacross the said chamber,having sh :tnhs W] l ieh on ten d th rough thewall thereof, devices connected to said shanks to adjust and. hold thebars at ys'urying angles in one gmieral direction and at varying anglesin the opposite general directitm,whcreby said bars control the speed offeeding from the maximum to the minimum degree of slowness and from themaximum to the minimum degree of rapidity, one of said directions beingof a general slow feeding and the other of a general. faster feed, and acylindrical body on said shaft within said chamber, and havingj)eripheral lugs or projections which coact with said bars to crush andfeed the material.

In testi mony whereof I attix my signature in presence of two \vitnesJAMES l. \\'l N t H Elli).
